Facebook has released a major update to its iOS app focused on improving performance. In Facebook 5.0 major portions of the app have been rewritten in iOS native Objective-C code, rather than relying on the HTML5 code used for the browser-based Facebook mobile site. The result is an app that now performs significantly faster when loading and scrolling through news feeds and timelines. Several smaller user interface improvements have also been made in the new version, including the integration of Facebook Messenger features, the ability to open and close photos more quickly using upward and downward swipe gestures and a banner notification for new stories and comments, along with a few other minor cosmetic changes. Facebook 5.0 is a universal app requiring iOS 4.3 or later and is available from the App Store as a free download.
